Title: Guide to testing insecticides on coniferous forest defoliators

Author: Williams, Carroll B Jr.; Sharpnack, David A.; Maxwell, Liz; Shea, Patrick J.; McGregor, Mark D.;

Date: 1985

Source: Gen. Tech. Rep. PSW-85. Berkeley, Calif.: Pacific Southwest Research Station, Forest Service, U.S. Department of Agriculture. 38 p

Publication Series: General Technical Report (GTR)

Description: This report provides a guide to techniques for designing field tests of candidate insecticides, and for carrying out pilot tests and control projects. It describes experimental designs for testing hypotheses, and for sampling trees to estimate insect population densities and percent reduction after treatments. Directions for applying insecticides by aircraft and for evaluating the effectiveness of such applications on target and nontarget insects are explained. The guide can help practitioners improve decisionmaking, efficiency, and safety in the use of insecticides to control forest pests. Although it is based primarily on budworm populations, the information reported is applicable to other coniferous forest defoliators.

Keywords: insecticide tests, forest defoliators, western spruce budworm, Douglas-fir tussock moth, experimental designs, sampling
